Coherent Electron Control; Matter Optics with Intense Laser Light and Nanostructures

本实验研究项目的重点是量子力学电子波包的研究和控制。这种控制将被用来提高由PI小组开发的一种新的测量设备(光栅电子干涉仪)的灵敏度。这种控制也将被用来影响超短电子脉冲在目标上的传输。电子干涉仪和超短电子脉冲将被用来测试最基本的量子力学现象之一--阿哈罗诺夫-玻姆效应。这一效应也证明了局域规范不变性，这是构建我们最先进的物理理论的指导原则。这些工具不仅将使我们更好地理解基本量子力学，而且其技术影响延伸到电磁场传感器和时间分辨电子显微镜。更广泛的影响包括在研究环境中对本科生和研究生进行培训，以及采用互动教育方法开发课程。

This experimental research program focuses on the study and control of quantum mechanical electron wave packets. This control will be used to increase the sensitivity of a new measuring device (a grating electron interferometer) developed by the PI's group. This control will also be used to affect the delivery of ultrashort electron pulses on a target. The electron interferometer and the ultrashort electron pulses will be used to test one of the most fundamental quantum mechanical phenomena; the Aharonov Bohm effect. This effect is also a demonstration of local gauge invariance, which is a guiding principle in the construction of our most advanced physical theories.Not only will these tools allow better understanding of fundamental quantum mechanics, but the technological impact extends to electromagnetic field sensors and time resolved electron microscopy. The broader impact involves student training at the undergraduate and graduate levels in a research environment, as well as curriculum development employing interactive educational methods.
